Background: Risk factors and short-term mortality in patients presented with Acute Coronary Syndrome (ACS) in Bahrain has not been evaluated before. Aim: In this prospective observational study, we aim to determine the clinical risk profiles of patients with ACS in Bahrain and describe the incidence, pattern of presentation and predictors of in-hospital clinical outcomes after admission. Methods: Patients with ACS were prospectively enrolled over a 12 month period. The rate of incidence of risk factors in patients was compared with 635 non-cardiac patient admissions that matched for age and gender. Multiple logistic regression analysis was used to predict poor outcomes in patients with ACS. The variables were ages >65 years, body mass index (BMI) >28 kg/m2, GRACE (Global Registry of Acute Coronary Events) score >170, history of diabetes mellitus (DM), systolic hypertension >180 mmHg, level of creatinine >160 μmol/l and Heart Rate (HR) on admission >90 bpm, serum troponin rise and ST segment elevation on the ECG. Results: Patients with ACS (n=635) were enrolled consecutively. Mean age was 61.3 ± 13.2 years, with 417 (65.6%) male. Mean age for patients with ST-segment elevation myocardial infarction (STEMI, n=156) compared with non-STEMI (NSTEMI, n=158) and unstable angina (UA, n=321) was 56.5± 12.8 vs 62.5±14.0 years respectively. In-hospital mortality was 5.1%, 3.1% and 2.5% for patients with STEMI, NSTEMI, and UA, respectively. In STEMI patients, thrombolytic therapy was performed in 88 (56.5%) patients and 68 (43.5%) had primary coronary angioplasty (PCI). The predictive value of different clinical variables for in-hospital mortality and cardiac events in the study were: 2.8 for GRACE score >170, 3.1 for DM, 2.2 for SBP >180 mmHg, 1.4 for age >65 years, 1.8 for BMI >28, 1.7 for creatinine >160 μmol/L, 2.1 for HR >90 bpm, 2.2 for positive serum troponin and 2.3 for ST elevation. Conclusion: Patients with STEMI compared with NSTEMI and UA were of younger age. There was higher in-hospital mortality in STEMI compared with NSTEMI and UA patients. The most significant predictors of death or cardiac events on admission in ACS were DM, GRACE Score >170, systolic hypertension >180 mmHg, positive serum troponin and HR >90 bpm.

Aims To investigate the different risk factors among different subtypes of patients with acute coronary syndrome (ACS). Methods A total of 296 patients who had ACS were retrospectively enrolled. Blood and echocardiographic indices were assessed within 24 hours after admission. Differences in risk factors and Gensini scores of coronary lesions among three groups were analyzed. Results Univariate analysis of risk factors for ACS subtypes showed that age, and levels of fasting plasma glucose, amino-terminal pro-brain natriuretic peptide, and creatine kinase isoenzyme were significantly higher in patients with non-ST-segment elevation myocardial infarction (NSTEMI) than in those with unstable angina pectoris (UAP). Logistic multivariate regression analysis showed that amino-terminal pro-brain natriuretic peptide and the left ventricular ejection fraction (LVEF) were related to ACS subtypes. The left ventricular end-diastolic diameter was an independent risk factor for UAP and ST-segment elevation myocardial infarction (STEMI) subtypes. The severity of coronary stenosis was significantly higher in NSTEMI and STEMI than in UAP. Gensini scores in the STEMI group were positively correlated with D-dimer levels (r = 0.429) and negatively correlated with the LVEF (r = −0.602). Conclusion Different subtypes of ACS have different risk factors. Our findings may have important guiding significance for ACS subtype risk assessment and clinical treatment.

Objectives: We sought to assess whether plasma neopterin predicts adverse clinical outcomes in patients with NSTEACS. Background: Circulating C reactive protein (CRP), a marker of inflammation, correlates with events in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). High neopterin levels - a marker of macrophage activation - predict cardiovascular events in stable angina patients but their prognostic role in NSTEACS has not been systematically evaluated. Methods: We prospectively assessed 397 patients (74 % men) admitted with NSTEACS: 169 (42.5%) had unstable angina and 228 (57.5%) non-ST-segment elevation myocardial infarction (NSTEMI). Blood samples for neopterin and CRP assessment were obtained at admission. TIMI risk score was also assessed among other clinical and biochemical variables. The study end point was the composite of cardiac death, acute myocardial infarction and recurrent angina at 180-days. Results: Baseline neopterin concentrations (nmol/L) were similar in unstable angina and NSTEMI patients (8.3 [6.5–10.6] vs 8.0 [6.2–11.1], p = 0.54). Fifty-nine patients (14.9 %) had events during follow-up (highest third (%) 21.5 vs 1 st and 2 nd thirds 11.5, log rank 7.341, p = 0.007). On multivariable hazard Cox regression, only neopterin (highest vs 1 st and 2 nd thirds, HR 2.15, 95 % CI [1.21–3.81]) was independently associated with the combined endpoint.CRP levels, however, were not significantly different in patients with events compared to those without events (adjusted HR = 0.98, p = 0.89, 95% CI 0.80 –1.21). Conclusion: Increased neopterin levels are an independent predictor of 180-day adverse cardiac events in patients with NSTEACS.

Aims: The purpose of this study was to investigate the relationship between heart rate at admission and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Methods: Consecutive ACS patients admitted in 2008–2010 across 58 hospitals in six participant countries of the European Hospital Benchmarking by Outcomes in ACS Processes (EURHOBOP) project (Finland, France, Germany, Greece, Portugal and Spain). Cardiogenic shock patients were excluded. Associations between heart rate at admission in categories of 10 beats per min (bpm) and in-hospital mortality were estimated by logistic regression in crude models and adjusting for age, sex, obesity, smoking, hypertension, diabetes, known heart failure, renal failure, previous stroke and ischaemic heart disease. In total 10,374 patients were included. Results: In both STEMI and NSTE-ACS patients, a U-shaped relationship between admission heart rate and in-hospital mortality was found. The lowest risk was observed for heart rates between 70–79 bpm in STEMI and 60–69 bpm in NSTE-ACS; risk of mortality progressively increased with lower or higher heart rates. In multivariable models, the relationship persisted but was significant only for heart rates >80 bpm. A similar relationship was present in both patients with or without diabetes, above or below age 75 years, and irrespective of the presence of atrial fibrillation or use of beta-blockers. Conclusion: Heart rate at admission is significantly associated with in-hospital mortality in patients with both STEMI and NSTE-ACS. ACS patients with admission heart rate above 80 bpm are at highest risk of in-hospital mortality.

Abstract Introduction: The recent development of large networks dedicated to ST-segment elevation myocardial infarction (STEMI) led to a significant increase in the number of primary percutaneous interventions (p-PCI) parallel with mortality reduction in Acute Coronary Syndrome (ACS). The number of non ST segment elevation myocardial infarction (NSTEMI) is increasing and the highest mortality rates are encountered in patients with cardiogenic shock and/or out of hospital cardiac arrest associated to ACS. The aim of this study was to identify the factors associated with a higher mortality rate in a global population with acute coronary syndromes presented in the emergency department of a county clinical hospital which serves as a regional center for a STEMI network. Material and method: This is a retrospective study including 684 patients with acute coronary syndrome admitted in the Clinic of Cardiology from the County Clinical Emergency Hospital Tîrgu Mureș in 2014. In all the cases, the factors that correlated with in hospital mortality were identified and analyzed. Results: The incidence of arterial hypertension was significantly higher in patients admitted with unstable angina (75.0%) and STEMI cases with less than 12 hours onset of symptomatology (68.1%), while impaired renal function correlated with the presence of NSTEMI (66.6%). The presence of a multivessel disease was significantly correlated with cardiogenic shock. The localisation of the culprit lesion in the left anterior descending artery (LAD) significantly correlated with the development of cardiogenic shock, LAD culprit lesions being present in 44.4% of CS cases as compared with 21.7% of noCS cases in STEMI patients. In NSTEMI patients, the localisation of the culprit lesion in the left main artery (LM) significantly correlated with the development of cardiogenic shock, culprit lesions in the left main being present in 47.0% of CS cases as compared with 28.5% of noCS cases in STEMI patients. Conclusion: Patients presenting with out-of-hospital resuscitated cardiac arrest due to Acute Myocardial Infarction associate higher in-hospital mortality rates. In-hospital mortality seems to be highly correlated with the female gender, STEMI myocardial infarction and the presence of multivascular lesions.

Background: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI ) are common types of acute coronary syndrome which are associated with the risk factors of age, obesity, hypertension, and diabetes. Objective: The present study aimed to examine the effects of age on the risk factors and clinical symptoms of acute coronary syndrome. Methods: A cross-section prospective study was conducted on 125 patients with acute coronary syndrome chosen by non-probability convenience sampling method in the coronary care unit in Sulaimani, the Kurdistan region of Iraq. Acute coronary syndrome types were diagnosed through clinical presentations, electrocardiography (ECG), and troponin test. Data was collected using a researcherbased checklist through face-to-face interviews. Results: The results indicated that males were the dominant group. The age group 45-65 had the highest prevalence rate of acute coronary syndrome. The most frequent risk factors for acute coronary syndrome were hypertension (54.4%), dyslipidemia (52%), smoking (42.4%), and diabetes mellitus (38.4%). Typical chest pain was found to be the most frequent clinical presentation (88%). There was a significant difference between the age groups in terms of the effect of age on typical and atypical symptoms; however, neither age nor typical/atypical symptoms had a significant effect on type of acute coronary syndrome. Similarly, family history, hypertension, diabetes mellitus, obesity, smoking, physical inactivity, and dyslipidemia had no effect on type of acute coronary syndrome. Conclusion: Age is a predictive factor for acute coronary syndrome, but family history, hypertension, diabetes mellitus, obesity, smoking, physical inactivity, and dyslipidemia cannot predict acute coronary syndrome.

Introduction: In non-ST-segment elevation acute coronary syndrome (NSTE-ACS), ST-elevation in lead aVR (ST↑aVR) on admission ECG has been shown to be associated with severe coronary artery disease, but its impact on long-term clinical outcomes is unclear. Methods: We studied 454 patients with NSTE-ACS who underwent coronary angiography during initial hospitalization. Patients were divided into the 3 groups according to the degree of ST↑aVR on admission ECG: no ST↑aVR (n=301, G-A); ST↑aVR <1.0 mm (n=82, G-B); and ST↑aVR ≥1.0 mm (n=71, G-C). Troponin T (TnT), hemoglobin (Hb), estimated glomerular filtration rate (eGFR), brain natriuretic peptide (BNP), high-sensitivity C-reactive protein (hsCRP), TIMI risk score, and summed ST-segment depression in other leads were also measured on admission. Results: There were no differences in sex or coronary risk factors except for diabetes mellitus in the 3 groups. In G-A, G-B, and G-C, age was 66±11, 68±11, and 70±11 years; the rates of diabetes mellitus were 30%, 48%, and 51%; Killip class ≥2 was 7%, 20%, and 34%; positive TnT was 30%, 46%, and 56%; TIMI risk score was 2.8±1.4, 3.6±1.3, and 3.8±1.2; the levels of Hb were 13.4±1.9, 13.2±1.9, and 12.2±2.3 g/dl; eGFR was 65±24, 59±27, and 53±28 ml/min/1.73 m2; BNP was 155±249, 386±338, and 455±507 pg/ml; hsCRP was 0.339±1.499, 0.654±1.899, and 0.842±1.788 mg/dl; summed ST-segment depression was 2.0±2.6, 5.6±3.5, and 13.0±6.6 mm; the rates of left main or 3-vessel disease were 9%, 44%, and 75%; and major adverse events (death, [re]infarction, urgent revascularization, or heart failure requiring hospitalization) at 5 years were 19%, 43%, and 58%, respectively (all p<0.01). After adjusting for baseline characteristics, multivariate analysis showed that as compared with no ST↑aVR, the hazard ratios (95% CI) for 5-year adverse events associated with ST↑aVR <1.0 mm and ST↑aVR ≥1.0 mm were 2.16 (1.10-5.59; p=0.019) and 3.90 (1.44-9.76; p=0.001), respectively. Conclusions: In patients with NSTE-ACS, greater ST↑aVR on admission ECG strongly predicted 5-year adverse outcomes, even after adjusting for traditional risk factors, biomarker profiles, and ST-segment depression in other leads. Our findings suggest the importance of ST↑aVR in risk stratification for NSTE-ACS.

Aim.To identify the risk factors for bleeding of BARC scale 2-5 types in patients after acute coronary syndrome (ACS).Material and methods.The data of 1502 patients from the open multicenter study, ORACUL II, were used — 894 men (59,5%) and 608 women (40,5%), mean age — 65,7±12,9 years. Five hundred sixty (37,3%) patients had ACS with ST-segment elevation and 942 (62,7%) — ACS without ST-segment elevation. Bleeding was recorded in 164 patients (10,9%), including index admission — in 39 (2,6%) patients, of which severe (types 3-5) — 0,5%, significant — 1,7% (types 2-5).Results.Within a year after discharge, bleeding was observed in 126 (8,4%) patients, large — 0,8%, significant — 2,4%. The development of bleeding type 2-5 was associated with the presence of gastric ulcer and duodenal ulcer, gastrointestinal bleeding in history, decreased creatinine, hemoglobin clearance, age of patients, the use of anticoagulants in the composition of triple or double antithrombotic therapy, conducting of percutaneous interventional procedures, the presence of heart failure 2-4 Killip class at admission. ROC analysis showed that the predictive value of the ORACLE bleeding risk scale is 0,762, sensitivity — 62%, specificity — 78%.Conclusion.Thus, we based on routine clinical practice have created a simple scale for assessing the risk of bleeding in patients with ACS.

Objective: to study the risk factors for acute renal injury, the dynamics of renal function and prognosis in patients with acute coronary syndrome with ST-segment elevation (STEACS) with contrast-induced nephropathy (CIN) after primary percutaneous coronary intervention (PCI).Materials and methods. We studied 20 patients with STEACS, who developed СIN after PCI (follow-up group), and 98 patients with STEACS without СIN (comparison group). All patients were measured plasma creatinine level and glomerular filtration rate by the formula CKD-EPI before and 48 hours after PCI. CIN was detected with an increase in creatinine levels in the blood by more than 26.5 µmol / l from the baseline 48 hours after administration of radiopaque drug (RCP). Endpoints were evaluated at the hospital stage and within 12 months after PCI.Results. CIN after PCI occurred in 16.9 % of patients with STEACS. Among patients with СIN, persons aged over 75 years (60 %), with diabetes mellitus (45 %), chronic kidney disease (75 %), postinfarction cardiosclerosis (50 %), chronic heart failure of functional class III–IV (80 %), developed acute heart failure T. Killip III–IV (90 %) were significantly more often observed. The left ventricular ejection fraction was lower in patients with СIN (p <0.05). The average increase in plasma creatinine 48 hours after PCI was higher in the follow-up group (p <0.05). In patients with СIN more often, than without СIN, three-vascular lesions of the coronary bed were detected (65 and 25.5 % respectively, p <0.001). The same trend was observed, when assessing the average number of coronary artery stenoses, the number of implanted stents and the volume of RCP used. Patients with СIN, than without СIN, were longer in hospital (12.1 ± 0.96 and 10.2 ± 1.11 days respectively, p <0.05) and more often needed re-hospitalization within 12 months after PCI (34 and 4.1 % respectively, p <0.05).Summary. CIN in patients with STEACS after primary PCI was more likely to develop, if the following symptoms were present: age over 75 years, diabetes mellitus, chronic heart failure, post-infarction cardiosclerosis, chronic kidney disease, low ejection fraction of the left ventricle, initially high creatinine level, development of acute heart failure, trisovascular coronary lesion and multiple coronary stenting. The duration of hospital stay and the frequency of re-hospitalizations within a year after PCI significantly increased in patients in the CIN group.

The patients presenting acute coronary syndrome without ST segment elevation can have a short and long-term risk of death or recurrent ischemic events. Therefore, the evaluation of risk is an essential step in the management of such patients. We report two cases – a 86-year-old male, and a 46-year-old one – with acute coronary syndrome with non-ST-segment elevation, showing the importance of risk assessment to determine management strategy. Two risk profile scores were used: TIMI score and GRACE score. Routine use of validated risk score may facilitate more appropriate tailoring of intensive therapies, but the clinical reasoning of the physician is essential to take right decisions.
